METHOD FOR MANUFACTURING MICROFILTRATION MEMBRANE AND HIGH FLUX MICROFILTRATION MEMBRANE MANUFACTURED THEREFROM

摘要

PURPOSE: A method for manufacturing a microfiltration membrane and a high flux microfiltration membrane manufactured by the same are provided to secure the water penetrating performance of the microfiltration membrane. CONSTITUTION: Poly vinylidene fluoride and inorganic salt are mixed with an organic solvent to obtain a polymer solution. The polymer solution is defoamated and is casted on non-woven fabric. Hollow fiber shaped membrane is obtained. The membrane is immersed in distilled water and is coagulated. The solvent remained in the membrane is eliminated, and a drying process is followed with respect to the membrane.
